Fun fact, color is determined by the wavelength of light that is not absorbed by an object and bounces back to your eyes. Black absorbs every wavelength on the visible spectrum, and as such it would be best represented as the absence of any color, but here's a weird thing for you to think on; Black could very easily be extremely colorful, but the human eye can only detect a very limited spectrum of colors. It is totally reasonable to assume that even if an object is black, there are still light wavelengths it reflects, but those wavelengths are likely part of the 98% of all wavelengths that are not visible to the human eye.
